[0009] [1] The bathtub disclosed herein comprises a sheet-made bathtub body that is used by filling it with hot and cold water while suspended, a rope for suspending the bathtub body, and an adjustment unit for adjusting the length of the rope. With this configuration, the shape and size of the suspended bathtub can be changed by adjusting the length of the rope. [2] In the bathtub described in [1] above, the rope may have a main body that is positioned along the upper edge of the bathtub body when suspended, and the main body may not be fixed to the upper edge of the bathtub body. This configuration makes it easy to replace the rope. [3] In the bathtub described in any of [1] to [2] above, the end of the rope may have a hook that can be hooked onto a hanging member installed in the bathroom, and the hook may be fixed to a corner of the upper edge of the bathtub body. With this configuration, the corner of the upper edge of the bathtub body is less likely to shift from the position of the hook, so the shape and size of the bathtub can be maintained. [4] The bathroom of the present disclosure is equipped with a hanging member for hanging a bathtub described in any of [1] to [3] above.

[0010] <Embodiment 1> The bathtub 10 in embodiment 1 is placed in a bathroom 50, as shown in FIG. 1. The bathroom 50 includes a wall W, a ceiling C, a floor F, a faucet device 60, and four hanging members 70. The faucet device 60 and hanging members 70 are fixed to the wall W. The wall W includes walls W1, W2, and W3 connected to each other, and a wall (not shown) facing wall W3. The wall (not shown) has an entrance / exit for passing between the adjacent changing room and the bathtub. A door is provided at the entrance / exit. The floor F has a gentle downward slope toward a drain (not shown).

[0011] Bathroom 50 does not have a freestanding bathtub. Bathtub 10 is placed along wall W3 of bathroom 50. When bathtub 10 is installed in bathroom 50, a washing area for bathers to wash their bodies is formed on the entrance / exit side of bathroom 50. Bathtub 10 is detachable from bathroom 50. By removing bathtub 10, bathroom 50 can be conveniently used as a shower room.

[0012] The faucet device 60 is a shower device. The faucet device 60 has a faucet 61, a water outlet pipe 62, an overhead shower 63, and a hand shower 65. The faucet 61 is connected to a water supply pipe and a hot water supply pipe (not shown). The faucet 61 is a mixer faucet. The faucet 61 can adjust the temperature of the hot and cold water being discharged, adjust the amount of hot and cold water being discharged, switch between water discharge and stop, switch the flow path, etc. The faucet 61 can select either the water outlet pipe 62, the overhead shower 63, or the hand shower 65 to discharge hot and cold water. The hot water or cold water discharged from the faucet device 60 is referred to as hot and cold water regardless of the temperature, the mixing ratio of hot and cold water, etc.

[0013] The water outlet pipe 62 extends from the faucet 61. The water outlet pipe 62 extends in a direction away from the wall W1. The overhead shower 63 is provided above the faucet 61. The overhead shower 63 is connected to the faucet 61 via piping 67. The piping 67 extends vertically upward from the faucet 61 along the wall W1 and is bent at its upper end in a direction away from the wall W1. The overhead shower 63 is provided at the tip of the piping 67. The hand shower 65 is connected to the faucet 61 via a hose 69. The hand shower 65 is movable within the length of the hose 69.

[0014] A hooking portion 26 of the bathtub 10, which will be described later, is hooked onto each hanging member 70. Each hanging member 70 is bent in a J-shape so that the hooking portion 26 can be hooked from above (see FIG. 4). The hanging members 70 are provided on two opposing walls W1 and W2 of the wall W. Two hanging members 70 are provided on each opposing wall W1 and W2, for a total of four. The two hanging members 70 provided on each wall W1 and W2 are spaced apart horizontally. The two hanging members 70 provided on wall W1 are located below the faucet 61. The distance between the two hanging members 70 provided on wall W2 is the same as the distance between the two hanging members 70 provided on wall W1. The four hanging members 70 are arranged at the same height.

[0015] The bathtub 10 comprises a bathtub body 20 and a rope 30. The bathtub body 20 is made of a sheet. The bathtub body 20 takes on a boat shape when hung from a hanging member 70 and filled with hot water. The state in which the bathtub body 20 is hung from the hanging member 70 and filled with hot water is referred to as the in-use state.

[0016] When in use, the bathtub body 20 has a bottom surface 11 and side surfaces 12. When in use, the bottom surface 11 comes into contact with the floor F. This allows the floor F to support most of the load of the bathtub 10 when in use. When in use, the side surfaces 12 rise upward, surrounding the bottom surface 11. This allows the bathtub body 20 to hold an amount of hot water suitable for bathing.

[0017] The side surface portion 12 has a first side surface portion 21, a second side surface portion 22, a third side surface portion 23, and a fourth side surface portion 24. The first side surface portion 21, the second side surface portion 22, the third side surface portion 23, and the fourth side surface portion 24 are continuous and surround the bottom surface portion 11.

[0018] The bathtub body 20 is made of a single sheet material 13 cut to a predetermined shape. The sheet material 13 has little elasticity, and is able to maintain the shape of the bathtub body 20 in a boat-like shape when in use. The sheet material 13 is flexible, impermeable (waterproof), and durable against tension.

[0019] The sheet material 13 may be made by overlapping multiple materials. The multiple materials may be bonded with an adhesive. As a specific example, the sheet material 13 may have a two-layer structure in which a polyester fabric and a polyurethane film are laminated. The polyester fabric may be placed on the side of the sheet material 13 that forms the outer surface of the bathtub body 20, and the polyurethane film may be placed on the side of the sheet material 13 that forms the inner surface of the bathtub body 20. The inner side of the bathtub body 20 is the side where hot and cold water is stored, and the outer side of the bathtub body 20 is the side opposite the side where hot and cold water is stored.

[0020] As shown in Figure 2, the upper edge portion 15 of the bathtub body 20 has a rectangular shape when viewed from above in use. The upper edge portion 15 of the bathtub body 20 is the upper edge of the side surface portion 12. The upper edge portion 15 of the bathtub body 20 has a pair of short sides 16 and a pair of long sides 17. The first side surface portion 21 and the second side surface portion 22 extend downward from each of the pair of long sides 17. The third side surface portion 23 and the fourth side surface portion 24 extend downward from each of the pair of short sides 16.

[0021] The length of the short side 16 is set to be the same as the shoulder width of an adult male. The length of the short side 16 may be approximately 500 mm. The length of the long side 17 is set to be a dimension that allows an adult male to sit comfortably inside the bathtub body 20. The length of the long side 17 may be approximately 1600 mm.

[0022] Folded portions 14 are formed on a pair of long sides 17. As shown in Figure 3, the folded portions 14 are formed by folding the outer edge of the sheet material 13 to the outside of the bathtub body 20. The folded portion of the sheet material 13 is folded in three and sewn. The folded portions 14 are tubular and extend along the upper edge 15 of the bathtub body 20. The step created by forming the folded portions 14 is formed on the outside of the bathtub body 20.

[0023] As shown in Figure 2, the bathtub body 20 has an insertion section 25 and an adjustment section 80. The insertion section 25 is a folded section 14 provided along the long side 17 of the upper edge section 15 of the bathtub body 20. The insertion section 25 is cylindrical. The rope 30 is inserted inside the insertion section 25.

[0024] The insertion section 25 is formed continuously over the entire length of the long side 17 of the upper edge 15 of the bathtub body 20. The insertion section 25 has a double structure formed by folding back the sheet material 13, and therefore functions to reinforce the upper edge 15 of the bathtub body 20 together with the rope 30. When in use, the long side 17 of the upper edge 15 of the bathtub body 20 is less likely to bend downward. This allows the boat-shaped shape of the bathtub body 20 to be maintained without providing the rope 30 on the short side 16, and allows the bathtub body 20 to hold sufficient hot water. The adjustment sections 80 are provided at the four corners of the upper edge 15 of the bathtub body 20. The adjustment sections 80 will be explained in more detail later.

[0025] As shown in Figure 2, the rope 30 is arranged along the long side 17 of the upper edge 15 of the bathtub body 20 when in use. The rope 30 has a tensile strength that will not break even if a person sits on the upper edge 15 of the bathtub body 20 when in use. A polyester rope may be used for the rope 30. The rope 30 runs the entire length of the insertion section 25 from the wall W1 side to the wall W2 side.

[0026] The rope 30 has a main body portion 31 and engaging portions 26. The engaging portions 26 are provided at both ends of the rope 30 in the extension direction. The main body portion 31 is the portion of the rope 30 between the engaging portions 26. The main body portion 31 is inserted into the insertion portion 25. The main body portion 31 is not sewn to the insertion portion 25, for example.

[0027] The engaging portion 26 is hooked onto a hanging member installed in the bathroom. The rope 30 is suspended between walls W1 and W2 by hooking the engaging portion 26 onto the hanging member 70. As shown in FIG. 4, the engaging portion 26 is a loop formed by folding back the end of the rope 30 pulled out from the insertion portion 25. As shown in FIG. 4, the folded back end of the rope 30 is inserted into a through-hole 28 (described later) from inside the bathtub body 20, and is prevented from slipping out by a knot 32 formed on the outside of the bathtub body 20, as shown in FIG. 5. The knot 32 is formed by tying the end of the rope 30 into a knot. The knot 32 is positioned on the outside of the bathtub body 20 and is hooked onto the peripheral portion 29 of the through-hole 28. This secures the engaging portion 26 to the corner of the upper edge 15 of the bathtub body 20.

[0028] As shown in Figures 4 and 5, the adjustment portion 80 has a reinforcing sheet 81 and a knotting portion 32. Like the sheet material 13, the reinforcing sheet 81 may be a fabric or the like that has little elasticity and is flexible, impermeable (waterproof), and resistant to tension. The reinforcing sheet 81 is attached by overlapping it to the corner of the upper edge portion 15 of the bathtub body 20. The reinforcing sheet 81 is placed on the outside of the bathtub body 20 and sewn. The reinforcing sheet 81 extends continuously from the short side 16 to the long side 17. The reinforcing sheet 81 has a shape surrounded by the short side 16, the long side 17, and a circular arc 82. The circular arc 82 extends between the short side 16 and the long side 17.

[0029] A through hole 28 is formed in the adjustment portion 80. The through hole 28 has a circular shape. The through hole 28 penetrates both the sheet material 13 and the reinforcing sheet 81. A peripheral edge 29 of the through hole 28 is closed by an eyelet.

[0030] The length 30L of the rope 30 is adjusted in stages at the adjustment unit 80. The length 30L of the rope 30 is the length of the entire length of the rope 30 excluding the excess length 33. The excess length 33 is the length from the end of the rope 30 to the knot 32.

[0031] The length 30L of the rope 30 can be adjusted in stages by changing the position of the knot 32. By moving the position of the knot 32 closer to the end of the rope 30, the excess length 33 becomes smaller. By reducing the excess length 33, the length 30L of the rope 30 becomes larger. By moving the position of the knot 32 farther from the end of the rope 30, the excess length 33 becomes larger. By increasing the excess length 33, the length 30L of the rope 30 becomes smaller.

[0032] If the rope 30 becomes stretched over time due to use of the bathtub 10, the user can restore the length 30L of the rope 30 by increasing the excess length 33 by the amount of stretch. The rope 30 can be removed from the bathtub body 20 by untying the knot 32, so the user can easily replace the rope 30.

[0033] An example of a method for bathing using bathtub 10 will be described below. First, the bather sets up bathtub 10 in bathroom 50. Specifically, the bather sets up bathtub 10 by hooking engaging portion 26 of bathtub main body 20 onto hanging member 70 of bathroom 50. The bather can easily set up bathtub 10 in bathroom 50 by simply hooking engaging portion 26 onto hanging member 70.

[0034] At this time, the bather can adjust the length 30L of the rope 30. The bather may adjust the length 30L of the rope 30 before hooking the engaging portion 26 to the hanging member 70, or may adjust the length 30L of the rope 30 after hooking the engaging portion 26 to the hanging member 70.

[0035] Specifically, the bather can change the length 30L of the rope 30 by changing the position of the knot 32. By increasing the length 30L of the rope 30, the bather can lower the height position of the upper edge 15 of the bathtub main body 20. This allows the bather to make the bathtub 10 shallower and wider horizontally. On the other hand, by decreasing the length 30L of the rope 30, the bather can raise the height position of the upper edge 15 of the bathtub main body 20 and stretch the upper edge 15 taut between the walls W1 and W2. This allows the bather to make the bathtub 10 deeper and taller vertically.

[0036] Next, the bather fills the bathtub main body 20 with hot water. Specifically, the bather operates the faucet device 60 in the bathroom 50 to pour hot water at the appropriate temperature into the bathtub main body 20. The bather can lower the water level by making the bathtub 10 shallow and wide horizontally. The bather can raise the water level by making the bathtub 10 deep and vertically upright. Once the bather has poured the amount of water appropriate for their bathing method into the bathtub main body 20, they stop the faucet device 60 from discharging. The bottom surface 11 of the bathtub 10 comes into contact with the floor F when filled with hot water.

[0037] Next, the bather enters the bathtub 10. Because the bottom surface 11 of the bathtub 10 is in contact with the floor F, the weight of the water in the bathtub body 20 and the weight of the bather are largely supported by the floor F. If the water level is lowered, the bather can take a partial bath, submerging part of the body, or a reclining bath, lying down in the bathtub 10. If the water level is raised, the bather can take a full-body bath, submerging the entire body, or a semi-sitting bath, sitting or squatting in the bathtub 10. In this way, the bather can take a variety of bathing methods using the sheet bathtub 10. Because the rope 30 is not inside the short side 16 of the bathtub body 20, the bather can feel only the softness of the fabric when placing their head or legs on the short side 16 of the bathtub body 20, allowing for a relaxed bath.

[0038] When the bather has finished bathing, he or she removes the drain plug (not shown) from the bathtub main body 20 to drain the hot and cold water. The bather then removes the bathtub 10 from the walls W1 and W2. The bather can easily remove the bathtub 10 from the walls W1 and W2 by simply removing the circular rope 18 of the attachment part 26 from the hanging member 70. The bather then washes the removed bathtub 10 and hangs it on a faucet device 60 or the like to dry it. The bather then folds the bathtub main body 20 to make it compact and stores it outside the bathroom. Even if the rope 30 becomes stretched over time due to use of the bathtub 10, the bather can easily replace it with a new rope 30.

[0039] The embodiment configured as described above provides the following advantages. The bathtub 10 comprises a sheet-made bathtub body 20, a rope 30, and an adjustment unit 80. The bathtub body 20 is used by filling it with hot and cold water while suspended. The rope 30 suspends the bathtub body 20. The adjustment unit 80 adjusts the length 30L of the rope 30. With this configuration, the shape, size, etc. of the bathtub 10 in its suspended state can be changed by adjusting the length 30L of the rope 30.

[0040] The rope 30 has a main body 31. The main body 31 is arranged along the upper edge 15 of the bathtub body 20 when it is suspended. The main body 31 is not fixed to the upper edge 15 of the bathtub body 20. This configuration allows the rope 30 to be easily replaced.

[0041] The end of the rope 30 has an engaging part 26 that can be hooked onto a hanging member 70 provided in the bathroom 50. The upper edge 15 of the bathtub body 20 is fixed to the engaging part 26. With this configuration, the upper edge 15 of the bathtub body 20 is less likely to shift position at the engaging part 26 of the rope 30, so the shape and size of the bathtub 10 can be maintained.

[0042] <Embodiment 2> Next, a bathtub 10 and a bathroom 50 according to a second embodiment of the present disclosure will be described with reference to FIGS.

[0043] The bathtub 10 and bathroom 50 of this embodiment differ from embodiment 1 in that the knot 32 is hidden by a reinforcing sheet 81. Note that the same components as in embodiment 1 are given the same symbols and redundant explanations will be omitted.

[0044] The bathtub 10 of this embodiment, like embodiment 1, comprises a bathtub body 20, a rope 30, and an adjustment part 80. As in embodiment 1, the adjustment part 80 is provided at the four corners of the upper edge part 15 of the bathtub body 20. As in embodiment 1, the reinforcing sheet 81 is layered on the outside of the bathtub body 20 and sewn to the sheet material 13. A storage space 83 is formed between the reinforcing sheet 81 and the sheet material 13.

[0045] The adjustment portion 80 has a through hole 28 formed therein, similar to the first embodiment. The through hole 28 is formed only in the reinforcing sheet 81, and is not formed in the sheet material 13.

[0046] As in the first embodiment, the engagement portion 26 is formed by folding back the end of the rope 30 pulled out from the insertion portion 25. As shown in Figure 7, the folded back end of the rope 30 is inserted into the through-hole 28 from the outside of the bathtub body 20 and is prevented from slipping out by the knot 32. As in the first embodiment, the knot 32 is hooked onto the peripheral portion 29 of the through-hole 28, and the engagement portion 26 is fixed to the corner of the upper edge 15 of the bathtub body 20.

[0047] The knot 32 is arranged in the storage space 83. Because the knot 32 is hidden by the reinforcing sheet 81, the appearance of the bathtub 10 can be improved. The knot 32 can be taken out of or put into the storage space 83 via the removal section 84. The removal section 84 may be formed by not sewing a portion of the arc 82 of the reinforcing sheet 81 to the sheet material 13. The bather can change the length dimension 30L of the rope 30 by removing the knot 32 from the storage space 83 and changing the position of the knot 32.

[0048] As described above, in this embodiment, similarly to the first embodiment, by adjusting the length 30L of the rope 30, the shape, size, etc. of the bathtub 10 in the suspended state can be changed.

[0049] <Embodiment 3> Next, a bathtub 10 and a bathroom 50 according to a third embodiment of the present disclosure will be described with reference to Figures 8 and 9. The bathtub 10 and the bathroom 50 of this embodiment differ from the second embodiment in that the adjustment unit 80 does not have a through-hole 28. Note that the same components as those of the second embodiment will be assigned the same reference numerals and redundant explanations will be omitted.

[0050] The bathtub 10 of this embodiment, like embodiment 2, comprises a bathtub body 20, a rope 30, and an adjustment part 80. As in embodiment 2, the adjustment part 80 is provided at the four corners of the upper edge part 15 of the bathtub body 20. As in embodiment 2, the reinforcing sheet 81 is layered on the outside of the bathtub body 20 and sewn to the sheet material 13. As in embodiment 2, an accommodation space 83 is formed between the reinforcing sheet 81 and the sheet material 13. The accommodation space 83 is connected to the insertion part 25 via a communication part 85.

[0051] As in the second embodiment, the engagement portion 26 is formed by folding back the end of the rope 30 that has been pulled out from the insertion portion 25. The folded back end of the rope 30 is then reinserted into the insertion portion 25 from the other end of the insertion portion 25. The end of the rope 30 that has been inserted into the insertion portion 25 passes through the communication portion 85 and enters the storage space 83, where it is prevented from slipping out by the knot 32. The knot 32 is large enough that it cannot pass through the communication portion 85, and is caught on the periphery of the communication portion 85. As in the second embodiment, the bather can change the length 30L of the rope 30 by removing the knot 32 from the storage space 83 and changing the position of the knot 32.

[0052] As described above, in this embodiment, similarly to the second embodiment, by adjusting the length 30L of the rope 30, the shape, size, etc. of the bathtub 10 in the suspended state can be changed.

[0053] <Embodiment 4> Next, a bathtub 10 according to a fourth embodiment of the present disclosure will be described with reference to Figure 10. The bathtub 10 of this embodiment differs from the first embodiment in that the adjustment unit 80 does not have a through-hole 28. Note that components similar to those of the first embodiment are given the same reference numerals and redundant explanations will be omitted.

[0054] The bathtub 10 of this embodiment, like embodiment 1, comprises a bathtub body 20, a rope 30, and an adjustment part 80. As in embodiment 1, the adjustment part 80 is provided at the four corners of the upper edge part 15 of the bathtub body 20. As in embodiment 1, the reinforcing sheet 81 is layered on the outside of the bathtub body 20 and sewn to the sheet material 13.

[0055] The adjustment part 80 has a belt-shaped member 86. The belt-shaped member 86 is attached to the outside of the bathtub main body 20. The belt-shaped member 86 is in the form of a roughly rectangular sheet, and extends along the upper edge 15. The belt-shaped member 86 may be a flat string made by arranging several threads flat and solidifying them with glue. Both longitudinal ends of the belt-shaped member 86 are sewn to and fixed to the reinforcing sheet 81. A threading portion 87 is formed between the belt-shaped member 86 and the reinforcing sheet 81. The threading portion 87 is large enough to pass the rope 30 through.

[0056] As in the first embodiment, the engagement portion 26 is formed by folding back the end of the rope 30 pulled out from the insertion portion 25. The folded back end of the rope 30 passes through the threading portion 87 and is prevented from slipping off by the knot 32. The knot 32 is hooked onto the belt-shaped member 86, and the engagement portion 26 is fixed to the corner of the upper edge 15 of the bathtub main body 20. As in the first embodiment, the bather can change the length 30L of the rope 30 by changing the position of the knot 32.

[0057] As described above, in this embodiment, similarly to the first embodiment, by adjusting the length 30L of the rope 30, the shape, size, etc. of the bathtub 10 in the suspended state can be changed.

[0058] <Embodiment 5> Next, a bathtub 10 according to a fifth embodiment of the present disclosure will be described with reference to Figure 11. The bathtub 10 of this embodiment differs from the first embodiment in that the length 30L of the rope 30 is adjusted by an adjuster 88. Note that the same components as those in the first embodiment are designated by the same reference numerals, and redundant explanations will be omitted.

[0059] The bathtub of this embodiment, like embodiment 1, comprises a bathtub main body 20, a rope 30, and an adjustment unit 80. As in embodiment 1, the adjustment units 80 are provided at the four corners of the upper edge 15 of the bathtub main body 20. The rope 30 is belt-shaped. As in embodiment 1, the engagement unit 26 is formed by folding back the end of the rope 30 pulled out from the insertion unit 25. The folded back end of the rope 30 is passed through and fixed to an adjuster 88. By adjusting the position of the adjuster 88, the length dimension 30L of the rope 30 can be easily adjusted.

[0060] As described above, in this embodiment, similarly to the first embodiment, by adjusting the length 30L of the rope 30, the shape, size, etc. of the bathtub 10 in the suspended state can be changed.

[0061] <Embodiment 6> Next, a bathtub 10 and bathroom 50 according to a sixth embodiment of the present disclosure will be described with reference to Figure 12.
